Welcome to the lesson on basic airway technique. In this video, we'll discuss how to use three basic airways oropharyngeal, airway, nasal pharyngeal airway, and suctioning. When selecting an airway device, keep in mind that too large of an airway device can damage the throat in too small of an airway device can press the tongue into the airway. To insert an oral pharyngeal airway, or Oh PA, first, clear the mouth of blood and secretions with suction if possible. Place the device at the side of the individuals face. Make sure to choose a device that extends from the corner of the mouth to the earlobe.

Insert the device into the mouth so the point is toward the roof of the mouth or parallel to the teeth. Do not press the tongue back into the throat. Once the device is almost fully inserted, turn it until the tongue is cocked by the interior curve of the device. To insert a nasal pharyngeal airway, or NPA placed the device at the side of the individuals face. Make sure To choose a device that extends from the tip of the nose to the ear lobe, use the largest diameter device that will fit. Lubricate the airway with a water soluble lubricant or anesthetic jelly.

Insert the device slowly into a nostril moving straight into the face, not toward the brain. It should feel snug. Do not force the device into the nostril it feels stuck, then remove it and try the other nostril. Here are some tips on suctioning. When suctioning the oropharynx do not insert the catheter too deeply. Extend the catheter to the maximum safe depth instruction as you withdraw.

When sectioning an ET tube, remember the tube is within the trachea and you may be suctioning near the bronchi or lung. Therefore, sterile techniques should be used. Each section attempt should be for no longer than 10 seconds. Remember the individual will not get oxygen during suction. Monitor vital signs during suctioning and stop suctioning immediately if the individual experiences hypoxemia that is, oxygen sets less than 94% as a new arrhythmia, or become sign out. This concludes our lesson on basic airway techniques.

Next, we'll review automated external defibrillator.
